Abstract

Background: In Taiwan, illegal drug use is a critical health problem during adolescence. Schools playa vital role in preventing students’ illegal drug use. Accordingly, we developed and evaluated a school-based, drug-use prevention program integrating the theory of planned behavior (TPB) and health literacy for junior high school students. Aim: This study aimed to use a theory-based program to prevent students from illegal drug use in Taiwanese junior high school students. Methods: We recruited 648 junior high school students aged around 13–14 years (grades 7 to 8 students) from 14 selected schools: N = 323 in the experimental group, N = 325 in the comparison group. The experimental group received 10 45-min sessions of a theory-based drug-use prevention program. The comparison group received traditional didactic teaching and drug refusal skill training. We used a generalized estimating equation (GEE) to analyze data. Results: Results of paired t-tests indicated that drug-use health literacy and TPB-related variables improved in the experimental group. The GEE analyses indicated that participants in the experimental group also demonstrated significantly improved health literacy (p < 0.001) compared to the comparison group, especially for functional (p < 0.001) and critical health literacy (p = 0.017). The experimental group also showed significant post-intervention improvement in terms of subjective norm scores (p = 0.024). Conclusion: Study results demonstrated the effectiveness of a drug-use prevention program on health literacy and subjective norm through integrating the Theory of Planned Behavior and health literacy. The study supports that the future implementation of similar programs for junior high school students can integrate health literacy and subjective norms as two critical program components.
